IMPROVEMENT IN SOFA-BEDSTEADS.

Specification forming part of Letters Patent No. 145,508, dated December 16, 1873; application filed May 31, 1873.

To all whom it may concern Be it known that I, PETER J. LARsoN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Loimges, of which improvements the following is a full, clear, and

exact description, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure l represents a top or plan view of my improved lounge, and Fig. 2 a front elevation of the same.

Like letters of reference indicate like parts.

The object of my invention is to make a lounge that may be readily converted into a bedstead; and to that end my invention consists in certain novel features, hereinafter fully described -and particularly set forth, relating to the means employed for the purpose of accomplishing the object above stated.

In the drawing, A represents the frame or body, B the back, C the bolster, and D the bottom or seat, of the lounge. The frame or body is made suiciently deep to receive a false bottom and bedding. The part D ismade of slats, and may be either provided with a suitable cushion or upholstered, so as to constitute a comfortable seat. The bolster may also be upholstered.

It will be observed, upon reference to Fig. 2, that when these parts are arranged together in the manner there shown, they will constitute an ordinary lounge.

a a are links, by means of which the bolster is attached to the end of the seat-frame, and

e is a hook attached to the seat' and engaging a staple on the bolster for the purpose of retaining the latter in the position shown in Fig. 2. e e are hinges, by means of which the seat is attached to the upper front edge of the body of the lounge. c is a cord attached to the seat and to the free side of the bolster. The cord e is of such a length that it will allow the bolster to be turned on the links c ayuntil the bottom of the bolster passes a little beyond a line vertical to the seat, it being understood that the hook a is first detached from the staple in the bolster.

In order to unfold the lounge, the bolster is arranged in. the position last described, and the seat is then turned on its hinges until the bolster reaches the door.

E is a leg pivoted to the free lateral edge of the seat at the end opposite the bolster. When the lounge is unfolded, this leg, together with the bolster, supports the seat, which then constitutes a part of the bed-bottom. F is a false bottom, resting on suitable supports in the body of the lounge, and arranged suiciently low to admitof bedding being arranged thereon when the lounge is folded. F F are crosspieces centrally pivoted to the under side of the bottom F, and f is a spring attached thereto and exerting a pressure against one of the cross-pieces F. G G are cords attached to the under side of each end of the seat, and passing through eyes in the upper edge of the foot and head of the body or frame of the lounge. The

cords G G are made in two strands, and the end of each strand is attachedto the bottom F, so as to support the same in a horizontal position. By this means the bottom F is drawn up by the operation of unfolding the lounge, and occupies a position in the place of the unfolded seat D, thus making a broad bedbottom. II is a foot-board on the bottom F, and I is a folding-board hinged to the seat D, so as to serve as a continuation of the part H when the lounge is unfolded. G is a cord attached to the ends of the cross-pieces F. J is a hook attached to the upper part of the board H, and engaging a staple in the upper part of the board I for the purpose of holding the latter in a vertical position when the lounge is used as a bed. The cord G is attached to the hooked end of the hook J, so that the pieces F F will be drawn against the spring f when the boards II and I are attached to cach other by means of the said hook. K K are mortises into which the ends of the pieces F F pass when the cord G is tightened, and the bottom F is thus flrmly supported.

' Vhen the hook J is unhooked, the spring f throws the ends of the pieces F F from the mortises K K, and as the lounge is folded the bottom F sinks to its original position.

L is a head-board linked to the bolster by means of links like the links a a, so that the said board may be extended across the head of the bottom F when the lounge is unfolded.

M is a hook, by means of which the board L is attached to the back of the lounge. L' is a head-board resting on springs exerting a pressure against its inner face; and N is a cloth or other suitable check, attached to the bolster and to the board L', to limit the movement of the latter when operated upon bythe springs upon which it rests. When the board L is unfolded, the board L' moves into its place, and an even head-board is thus formed, eX- tending entirely across the bed-bottom. When the board L is folded, it crowds the board L' to its original position. 0 is a hook to retain the board L in its folded position. When the lounge is folded, the hook M engages a staple in the board L, and thus retains the lounge in its folded condition.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a folding lounge, the combination and arrangement of the vertically-sliding bottom F, the pivoted cross-pieces F', the spring j', the mortises K K, and the cord G', subst-an tially as and for the purposes specified.

2. In a folding lounge, the bolster C, linked or hinged to a folding bottom, and provided with the head-board L hinged or linked there to, and with the yielding board L', all arranged and operating together, substantially as and for the purposes specified.

PETER J. LAR-SON.
